STAlR-CARPET-SECURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 574,796, dated January5, 1897.

Application filed June 24, 1896. $erial No. 696,747. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD FRANKLIN GARDNER, a citizen of the UnitedStates, residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inStair-Oarpet-Securing Devices; and I do.

hereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improvement in stair-carpet securers and itconsists in the construction and arrangement of parts here inafterdescribed, and definitely pointed out in the claims.

The object of the invention is to provide a device which can be appliedsecurely to the riser of stairs with but little trouble and which willreceive the carpet and holding-button in such a manner that the same maybe quickly applied and readily removed.

The objects of the invention are attainedby the construction illustratedin the accompanying drawings, wherein like letters of referencedesignate corresponding parts in the several views, and in which- Figure1 is a central section through the device. Fig. 2 is an elevationshowing the device applied to the stair and a section of carpet inplace. Fig. 3 is a front elevation. Figs. 4 and 5 are plan views of theplate, showing the same in different adjustments.

In the drawings, A designates a fiat plate having at one end an openingB, formed with the countersunk edge and adapted to receive the head ofthe screw by which the plate is secured to the riser D. At the oppositeend of the plate A is a pointed pin E, rigidly secured to the plate andhaving its base formed cylindrical and screw-threaded to receive thethreads on an aperture formed in the button F, which latter may be ofany convenient or desirable style. j

In applying the device it is only necessary to place against the riserand force the screw in until its head is flush with the face of theplate. The screw-opening being at one side of the center of the plate,the screw can be readily driven in Without interference on the partof'the pin. When the plate is securely seated, the carpet is forced overthe pin and the button is secured on the threaded portion of the pin.The pin being rigid on the plate, there is no danger of the samebecoming detached therefrom, an objection existing in known forms ofthis class of devices.

An additional advantage of eccentrically mounting the plate is that thesame may be turned to bring the pin in proper position relative to thesteps, and thereby compensate for any irregularity between the plane ofthe screws at opposite sides of the riser.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. In a stair-carpet-securing device, the combination with a flat platehaving a screw secured at one end thereof adapted to be inserted in ariser, a pin at the opposite end and side having a threaded section atits base, and a button, substantially as described.

2. A stair-carpet-securing device, consisting of a flat oblong platehaving a countersunk opening at one end, and a rigid pointed pin at theopposite end permanently secured to the plate and formed with a threadedbase, and a button, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD FRANKLIN GARDNER.
